The designation “18×6.5-8” refers to a tire size, where 18 represents the tire’s overall diameter in inches, 6.5 indicates the tire’s width in inches, and 8 signifies the wheel rim diameter in inches that the tire is designed to fit. For example, this specific tire size is commonly found on smaller utility vehicles, go-karts, and some lawn and garden equipment. Thus, the tire will properly mount only on a wheel with an 8-inch diameter.
Understanding tire sizing is critical for ensuring vehicle safety and optimal performance. Using the correct tire size prevents issues such as improper handling, inaccurate speedometer readings, and potential tire failure. Historically, standardized tire sizing has evolved to provide manufacturers and consumers with a consistent method for matching tires to compatible wheels, leading to increased safety and operational efficiency.
